T/CSES 20-2021 The validation and evaluation specifications for sewage bioprocessing techniques

Scope

Main technical content: To ensure the scientificness and standardization of the verification and evaluation of wastewater biological treatment technologies, for emerging or improved wastewater biological treatment technologies that are based on certain scientific principles, have completed industrial trials or have been applied on a small scale, and have market promotion prospects, three types of indicators, namely environmental effect indicators, process operation indicators, and maintenance management indicators, were designed to establish a three-level indicator system; a testing method mainly based on quantitative testing and analysis and supplemented by qualitative description was determined, and the testing cycle, sampling frequency, and determination principles of sampling points during laboratory verification and on-site verification were stipulated respectively; a verification and evaluation method based on wastewater biological treatment technologies was established, and the performance declaration rate, pollutant removal rate, treatment effect stability, operation reliability, environmental friendliness, and economic efficiency of the wastewater biological treatment technologies were evaluated based on statistical analysis of the test data. Specific technical content includes: (1) Scope; (2) Normative reference documents; (3) Terms and definitions; (4) General principles; (5) Data collection; (6) Verification test indicators; (7) Verification test cycle, sampling frequency, and sampling points; (8) Sample collection and storage; (9) Verification test methods; (10) Verification data evaluation; (11) Appendix A - Wastewater flow measurement method; (12) Appendix B - Volatile fatty acid (VFA) detection method; (13) Appendix C - Power consumption measurement method; (14) Appendix D - Summary table of verification test water quality indicators
